BOTTLE CAP Filed July '2, 1946 2 Sheets-Sheet 2 Patented June 3, 1947UNITED STATES PAT OFF ICE BOTTLE CAPI- John oi Terry, Hollywood, one,Application July 2, 1946;SerialNo; $81 ,001 A This invention relatesto=a bottle cap and it is primarily an object of the invention toprovide a cap of this kind which can beremovably applied and which, whenin working position, affords a gas-tight seal.

6 Claims. (Cl. 215*45) Furthermore, it is an 'object of the invention toprovide a device of this kind which is particularly advantageous for usein connection with bottles having an outside bead at the discharge endof the bottle neck,'such as is provided in the well known type of milkbottles.

An additional object ofthe invention is to provide a cap which iseffectively held in applied position under the action-of a lever mountedupon the cap and which has associated therewith ahead-engaginghookmember possessing acertain degree of inherent resiliency.

The invention consists in the details oiconstruction and in thecombination-and arrangement of the several parts of my improved bottlecap whereby certain important advantages are attained, as will behereinafter more fully set forth In order that my invention may bebetter understood, I will now proceed to describe the same withreference to the accompanying drawings, wherein:

In the embodiment of the invention as illustrated in the accompanyingdrawings, the body 2 member -B":of the'capais iormed from onesheet ofmaterial of requisite dimensions, as'is clearly illustratedjin Figure 5of the drawings. 2 This body member 3 comprises a central circular head'l of desired radius and which is provided atone point on its peripherywith an extended tongue '2 which is rolled back upon itself to provide apivotal mountingwfor the'lever L, as willbe'hereinafter'more-particularly set forth) L Diametrically opposedtothe tongue 2,-the head l is provided with an extended fianget which isupwardly turned on the line a, (Figure 5) to-substantially right anglesto the head I. This flange 3 along the majorportionthereof is providedwith the slot 4', the inner edge of which is coplanar with the line a;as'is also clearly shown in Figure 5. This slottedifiange 3 provides aneffective guide for the hook member H to be hereinafter moreparticularlylreferred to.

The outermarginal portion I of each of the enlargements Bis disposedinwardly on a slight curvature so as toengage under the conventionalexternal bead 8 generally found at the "outer or discharge extremity ofa bottleneck 9, such as the type used in connection with milkand thelike. i

The lever 'L, as illustrated in Figures 7' 'and 8, is also formed-from"a single 'blank or sheet of material and includes aflat shanklll'provided along itslongitudinal or-side edges with the wings II whichare turnedto substantially at right angles to-the' shank-l0; These wingsI I, as herein disclosed, are substantially triangular in form withtheir apices inwardlydisposedand the outer high points-of the-wings I l'are providedther'e through with the openings l2 which are intransversealignment. t

r The shank l0 in its outer 'end in substantially the same plane as theopenings I2 is provided transversely thereof with the slot l4 throughwhich the tongue 2 is freely directed, whereby the lever L is mountedupon the body of the cap for required swinging or rocking movement. Theouter end of the lever L has integrally formed therewith a flattenedfinger plate or piece I5 disposed on an angle of approximately 15 withreagianc or piece I5 in either applying or removing the cap..

The hook member H, as particularly illustrated in Figures 10 and 11, isformed from a single length of spring wire of requisite gauge formed toprovide the elongated parallel side arms I I in predetermined spacedrelation and coextensive in length one with the other. The adjacentextremities of these arms I1 are free but are continued 7 I by theinwardly disposed and transversely aligned trunnions I8 which aredisposed from without through the openings I2 in the wings II wherebythe hook member H is operatively engaged with the lever L whereby thehook member H will have substantial endwise movement in either directionacross the body of the cap, depending upon the rocking or swingingmovement of the lever L. It

is to be noted that the portions of the arms I! immediately adjacent tothe trunnions IB are disposed onan inward incline, as at I9, onpreferably an angle of 15 with respect to the major portion of the armsI I.

The extremities of the arm l! remote from the' trunnions I 8 areintegrally connected by a cross member formed to provide an inwardlyfacing hook bill 29 disposed preferably on an angle preferably of withrespect to the arms and which bill 20, when the lever L is at the limitof its movement inwardlyof the body I, is adapted to engage under thebead 8 of the container 9 when the lever is swung outwardly anddownwardly to lie close against the side of the container, as clearlyillustrated in Figure 1 of the drawings. When the lever L is in itsdownward or locking position, the cap as a unit is effectivelyheld inapplied position on the container 9 and'which position is furtherassured by the inherent resiliency of the h ok member H and moreparticularly the bill 20 thereof.

In close contact with the inner face of the head I and snugly heldbetween the flanges 5 is a sealing disk U of rubber or other suitablematerial and which disk 2I has direct contact with the outeredge surfaceof the container when the cap is applied thereto.

Before the hook member'H is operatively engaged with the lever L, thearms I1 thereof are threaded through the slot 4 of the flange 3, wherebysaid hook member is effectively guided in'its movement substantiallyradially across the head I. It is also to be pointed out that the slot 4is of 'a length whereby the flange 3 also provides an effective meansfor holding the arms I! against outward separating movement, wherebyaccidental disengagement of the 'trunnions I8 1' with the wings II ofthe lever L is substantially eliminated.

When the lever L is in released position, and with the cap in initiallyapplied position on the container 9 the flanges 5 of the head I and the4 bill 20 of .the hook member I-I contact the head of the container 9 ata point slightly below the center of the radius and at which time theceiling disk or gasket 2! is not under compression. When the lever L ismoved inwardly or downwardly, the bill 20 of the hook member H alsomoves downwardly whereby the disk or gasket 26 is put under compressionto effect a gas tight seal between the container and cap.

From the foregoing description it is thought to be obvious that a bottlecap constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated.

I claim:

1. A cap for a container having a neck With an exterior bead around theouter end of said neck, said cap comprising a head, marginal flangescarried by the head, said flanges having portions to engage under theexternal head of the container, a lever engaged with a marginal portionof the head for swinging movement, and a hook member extending acrossthehead and operatively engaged with the lever, said hook member having aninwardly disposed bill to engage the external bead of the container whenthe lever is swung in one direction.
